I got lucky with my first abyssea party. I had an ls buddy who invited me. Went from lvl 72-99 in a few hours. It was a cleave party so mad xp in altepa.

Oh another thing, you could make mad gil if you lvl leather craft to 30. Went to teleport-mea and farmed dhalmel hides. Had a stack of cluster, windurs tea leaves, and distilled water. Make dhalmel leather and sell for 100k. Materials will cost 5k per stack and profit margin of 95k. I farmed as thf/bst for widescan.

Once you get to lvl 90+ pick a main job and try to pimp it as much as possible. At one point I was trying to have 3 mains but it ended up costing too much. Thief is my main but since beast is much better for solo I am pursuing that too. Everything else is just to be more versatile. You won't get empy, mythic, or relic on every job you hit 99 with. That is a long term goal and would take years to accomplish if you pick many to pursue.

Don't be afraid shout for help. Chances are you will find a couple of bored people or who need what you need.

I had to send /tells to random people help for lb 95.

Make lots of friends. I usually duo with a smn friend of mine that I met through a casual ls. We kill a lot of nm's together.
